Be it known that I, EDWARD T. Burma,-

` a. citizen of the United-States, residing at Kansas' City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Pressing- Machines, of which the following is a specication.

My invention relates to steam pressing machines for pressing garments, clothes,

.etc., and one object of the invention is to provide novel means whereby the pressure of the pressing members is equally' distributed over the article being pressed.

A further object is to provide novel means whereby the degree of pressure exerted upon the articles being pressed can be regulated at the will of the operator and at a minimum expenditure of labor.

A further object is to provide means whereby the degree of heat and rapidity of circulation of the steam employed for heating the pressing members of the machine can be regulated at will'. VOther objects will hereinafter appear, and in order that said invention may be fully understood, reference will now be' ,made tothe accompanying drawings, in

which chine with its presser head in raised position.

Fig. 2 is a front elevation of the machine with the presser head in lowered position.

Fig. 3k isa plan view of the machine with the parts in the position disclosed by Fig. 2.

Fig. 4 is a broken plan view of the presser head. Y

Fig. 5 is -a longitudinal section of the presser head on line V-V of F 1g. 4.

Fig. 6 is a broken plan view of the bed of the machine.

Z'o allwhomtmay concern: hollow standard 4 secured upon the table 2.

tom plates 10 and 11 to form chambers 12 and 13, respectively, which vcommunicate with eachother through ports 14 surrounding screws 14, whereby the steam chest 9 and the plateslO and 11 are secured together. The ports 14 p ermit heat radiated from the top of the steam'chest 9 to pass from theu chamber 12 down into the chamber 13, and on commingling with the steam inthe latter escape through the perforations v 15'in the-bottom plate 11.

The bottom plate 11 is covered with a. cushion 11a to coact with the cushion 7 on the bed 3 in equalizing the pressure overthe have shown for this purpose a clamp 16- held in place by stud bolts 17 `and thumb nuts 18, which permit easy removal of said cushion 11a when desired. Bolts 17, are

.provided for connecting the two members of the clamp together.

The top of the presser head 8 is provided I with a pair of bearings 19 in which a rock shaft 2O is mounted carrying a handle 21, whereby said presser head 8 is lowered upon the bed 3. The shaft 20 is also mounted in a rock arm 22, which in turn is mounted upon a stationary shaft 23 mounted in a.

`bearing 24, secured to the upper portion of the pedestal 1. The ends of the shaft 23 are provided with rigidly mounted fittings 25, for a purpose which will hereinafter appear.

In order that the rock arm 22 may exert considerable downward pressure upon the presser head 8 when the same is lowered to the steam bed 3, and yet allow said presser head toA accommodate itself to any inequalf ties n the ,thickness of the cloth placed upon said bed 3, I provide the upper side Y of said presser head 8 with three screws 26, extending through openings in the rock arm 23 and eneircled by springs 27, bearing upon said rockarm 23. ATwo of the screws 26 are disposed at 'the rear of the rock shaft 20, while the other is at the front of said rock shaft, as disclosed by Figs. 1 and 3.

The rear end of the rock arm 22 is pivotally 4secured to a. connecting bar 28 pivot-v ally secured at its lower end to a link 29, which in turn is pivotally connected to a lug 30 extending rearwardly from the pedestal 1. yA counterweight 31`i's secured to Y the connecting bar 28 to normally -holdthe presser head 8 in raised position (Fig. l).

32 designates a tradle wherebyv eXtra pressure is applied tothe presser head 8 after the same has been lowered into contact with a garment upon the bed 3. Said treadle is fulcrumed to the pedestal 1 at 33 and provided at its rear end with a counterweight 34 to normally hold the forward end*- of said treadle'32 in' raised position. The link 29 and the upwardly curved rear end of thgotreadle 32 are so disposed with relation each other that when the former is raised by the lowering of the presser head 8 it will pass slightly -above the lower edge of the inclined-terminal of the treadle, so that when the same is actuated said inclined terminal contacts .and pushes ,the arm 29 upward and thus imparts the desiredv p .pressure to the presser head 8. 1

1 standing at the table 2.

43 designates a steam jet to exhaust condensed steam from the bed 3 through. the

pipe 40 andV` a communicating exhaust pipe 44. The jet 43 receives its steam from the piple 38 with which it communicates through a -coupling 45, and is provided withr a valve 46 for cutting off the flow of steam therethrough. V -v In addition to heating the lsteam bed 3 by steam discharged from the T-head 41, said bed is heated by steam radiated from a coil.

47, the twoflegs 48 4and 49 of, which pass through the hollow standard 4. The leg 48 receives steam from the pipe 38 with which it communicates through a T-coupling 50,

and the leg 9 communicates with a return pipe 51, which conducts the steam back into the lower portionof ,the boiler 36. A'drain cock 52 is connected to the lower portion of the'leg 49 to exhaust steam therefrom and thus cause the steam to circulate more rapidly and heat the. coil 47 to a higher degree Lamaze than when the steam is permitted to return -`to the boiler through, the pipe 51. Communicationv between the .steamybed 3 andthe neck-45s closed by a plate 40a, from which Y Steam .is conducted'from the boiler 36 to l -the steam chest 9 of the presser-head 8 through4 pipes 53 and 54, and returns from said steam chest to theboiler throughreturn pipes 55. and 56, and an injector 57 which communicates wlth said pipe 56 through. a

-coupling 58.- The injector 57 receives -its steam from the boiler through a pipe 59 and the pipe 38 which commuulcates through a T-coupling 60. The pipes 53 and 56 have rigid connections with the respective fittings 25,' while the pipes 54 and 55 are swiveled to said iittings, so that the last-mentioned pipes may rock withthe arm 22 when the presserhead 8 is raised and lowered.

Steam is admitted to the lower chamber 13 of the presser-headS through a pipe 63,

which communicates with the pipe 54 and is A provided with a valve 64 to control the flow of steam therethrough. The flow of steam through said pipes 63 is further controlled by a self-closing valve 65, embodying a lever 66 pivoted to a push rod 67, ex-

tending through the handle 21 and proyided with a knob 67a which can be readily operated bythe hand grasping said handle 21.

The boiler 36 has a superheating` steam coil 68 in its upper portion communicating with the pipes 38 and 53. 'A tank 69 is employed to provide a supply of feed water to the boiler with which it is connected by pipes 70 and 71. Pipe 70 leads from the upper part of a Steam chamber 72 to. the upper portion of the tank 69 to heat the water therein and also to force water into the. boiler through the pipe 71, which has a valve 73 and a check valve 74, which latter cuts off back pressure from the boiler. The pipe 70 is *providedy with a valve 75 to'control the flow ofsteam therefrom.

The tank 69 may be supplied from any suitable source, or it may be filled through a valve 76 at its upper end. As, approximately, all of the condensed steam 1s returned to the boiler 36, very little water need be drawn from the tank 69. Heat for generating-steam is applied through a suitable burner 77, placed beneath the boiler 36.

The heat from the burner circulates upwardly past water tubes 78 in the lower portion of the boiler, thence through a flue 79,

and escapes from the superheatl'ng chamber 80of the boiler through a1 stack 81.

From the foregoing description, it is apparent that I have produced a machine embodying all of theadvantages above enumerated, and while I have shown and described the preferred construction, combinatln, and arrangement of parts, I do not restrlct myself theretovbut reserve the right to make such changes as properly fall within the vspirit and scope of the claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: f
